Detailed Description
In order to make the technical means and the technical effects achieved by the technical means of the present invention clearer and more complete, the following embodiments are provided and are described in detail with reference to the accompanying drawings as follows:
as shown in fig. 1 to 7, the mold structure for automatically cutting off a gate of a direct glue injection type plastic product of the embodiment includes a mold body for injection molding, the mold body includes a front mold plate and a rear mold plate, a plastic part is formed on the rear mold plate, and the gate is formed between the plastic part and an injection molding runner; a cutting mechanism is arranged on the side part of the rear template; the cutting mechanism comprises a guide block arranged on one side of the rear template, a cutter box movably arranged in the guide block, a cutter fixed in the cutter box and partially extending out of the cutter and the front end, and a driving device connected with the rear end of the cutter box.
Preferably, drive arrangement adopts cylinder or electric jar, and the piston rod of cylinder or electric jar is fixed with the tool holder, and cylinder or electric jar are fixed with back template through a fixed block. The cylinder or the electric cylinder is adopted, so that the automatic cut-off and the automatic reset can be rapidly and accurately realized.
